ing compartn'lent of the retrigerati r box. My principal aim is to generally improve upon structures of this class by provlding one of comparative simplicity and "durabih ity, which isof such construction asto render it highly practical in operation and otherwise efficient in use.

Other iieatures and advantages of thein- I ventionwillbecome apparent from the fol lowing description and drawings.

In the accompanying drawings forining 1 part of this application and in which like 'nmnerals are employed to designate like parts throughout the sainet Figure 1 is a longitudinal section thru an ice box showingthe complete device arranged therein.

Fig. 2 is a perspective view of one embodiment of the device removed from the ice box. i

Fig. 3 is a view like Fig. 2, showing a oft-he invention.

Fig. 4 is a the structure shown in Flg. 3. Fig. 5 is a perspective view of one of the half sections or part of the cooler.

Attention is firstinvited to Fig.1, Wherein it will be seen that the reference character 1 designates an elongated ice box including a compartment 2 in which the improved device is movably mounted. This .ice box has a removable cover 3.

The principal part of the improved device comprises a box-like cooler which is composed of a pair of complemental half small view in bottom plan of eomprisesa hollow ice container which is Inclined on one side and provided in this inclinedside with a plurality of longitudr 7 ided for said top.

Asshownfbetter in Figs? and 3,this cover provided in its swingable edge with "notches" which are located for alinenlent with *the channels, so as not to obstructcirculation of the air. The complemental half section 5 is also in the form of an ice container and this is of somewhat triangular configuration in "end elevation. The inclined side thereof rests against the correspondingly inclined side of the first-named section 4 as shown i'plainly in Fig. 1. This side is provided with arcuate or segmental extensions "9 of hollow configuration and these are =located-for reception in the air circulating channel 6.

Attention is directed to the fact that the channels are slightly deeper than-the tongues 9 thus providing air circulating ipassages between the comp'lemental surtt'aces'of the tongues. and the walls of the channels. This section 'of the box is also open at itstop, and hinged cover 10 of solid-dorm is provided therefor. Obviously,

I when the two sections of the box are placed in sniperposed relation, they provide a two- .part container, of rectangular outline, in end elevation.

By considering Fig. 5 it will be noticed whereas in Fig. 2 it also comprises a pipe 13 connected with the front wallof the section 5 through the medium of branches 14. The pipe 13 is alsorprovided with a discharge neck 15. In Fig. 3, these pipes are not provided, owing to the special configuration of the channels and tongues. In this arrangement, the channels and tongues are disposed on the under side of the box as represented in-Fig. 4. However, they are designated by the same reference characters for they are substantially the same as already described. In the form of the structure shown in Figs. 3 and 4t, I simply provide two discharge necks 16 and 17 for the sections 4 and 5 respectively, these being located at one end ofthe structure as seen better in Fig. 4. Of course, the construction of the means,

for draining the containers depends a great deal on the location of the drain pipe 18 in theice box.

In all of the embodiments of the invention I provide an outer casing or housing for the superposed containers. For example in Fig. 1, I show an open top casing 19 having an opening 20 on its front side and at its bottom to accommodate the pipes 11 and 12. This constitutes a carriage and is provided with rollers 21 so that it can be moved about freely in the ice box. If desired, a spacing block 22 may be interposed between the sec tion 5 and the front wall of the casing. The same sort of a casing is provided in Fig. 2, except that supporting balls orlegs 23 are substituted for the rollers.

In the embodiment of the casing 24: shown in Figs. 3 and 4, the opening 25 instead of being in the front wall is located in the bottom for cooperation with the interiitting tongues and channels.

In practice, the box-like sections are filled with ice and are placed together so that the tongues extend into the channels. The Walls of the tongues and channels become cooled by the ice and as the air passes against the surfaces, it naturally cools off and circulates about the compartment of the ice boX.

It is believed that by carefully considering the description in connection with the draw-- ings, a clear understanding of the construction, the assembly of parts, the cooperation of the details, and the advantages of the new organizations will be quite clear. Therefore, a more lengthy description is thought unnecessary.

Minor changes coming within the field of invention claimed may be resorted to if desired.

tongues telescoping into and spacedfroin the walls of said channels, to provide curved air circulating pas ages. 1

2. In a structure of the class described, an air cooler comprising a box-like device composed of a pair of complemental sections,

each section comprising a hollow ice container, onesection being formed with channels, the other section being formed with tongues, said tongues telescoping into and spaced from the walls of said channels, to provide air circulating passages, said sections being open at their tops, and individual hingedly mounted members for said open tops.

3. In a structure of theclass described, a box-like device composed of a pair of complemental containers having inclined surfaces disposed in meeting contact, said meeting surfaces being provided with co-acting channels and tongues, said tongues extending into said channels, said channels and tongues cooperating in interfitting spaced relation to form air passages, and a casing for said device.

In testimony whereof I aflix my signature.
